Propotional system works only where the population is highly literate and the politicians are highly educated. That is what I understood. In context of Nepal, it's a win win situation for major parties with resource and cadres. Morever, when country's minimum needs and question of monarchy are attached together (two totally different subject)it will not reflect true people's aspirations but parties selfishness for sure. Referundum and CA should go together but messiah turned patries would give that choice to nepali? I don't think so.
